How is a pump defined in the context of fluid dynamics?

In fluid dynamics, a pump is fundamentally defined as a device that imparts energy to a fluid, enabling it to move from one location to another, specifically from Point "A" to Point "B." This energy is often provided in the form of mechanical energy, which the pump converts into kinetic or pressure energy within the fluid.

The primary function of a pump is to overcome resistance within the system, such as friction losses in piping, elevation changes, or pressure differentials, thus allowing fluids to be transported efficiently through various systems. Pumps are essential in applications ranging from industrial processes to municipal water supply, ensuring that fluids can be moved as needed for various purposes such as heating, cooling, or distribution.

Understanding this definition is crucial in the context of tankers and fluid transport, as the efficiency and effectiveness of moving large quantities of liquids depend on the proper operation of pumps.
